Oldham Athletic manager John Sheridan has expressed his disappointment at his side's second half performance against Walsall on Saturday.
Latics led at half time through Ryan McLaughlin but were pegged one back eight minutes into the second half.
Erhun Oztumer gave the home side the win on the stroke of 90 munites, when he converted from close range from a long throw-in.
"I feel as though we threw the game away, we were very comfortable in the first half and I think we deserved the lead." Said Sheridan.
"I was very comfortable, I thought we looked like a half decent side.
"But it’s criminal, you come out second half and I’m watching the same players, we’ve only had break for ten or 15 minutes, is there something in the water?
"I was just watching totally different players and performance [in the second half].
"I thought it was a great opportunity to get three points. You can not go out and perform and think you’re going to win a game just like that.
"I was watching players who I told at half time: ‘excellent, you’ve been excellent, keep it tight’. We went out for the second half and we weren’t at the races.
"I pick the team and I pick the players and I feel I need five or six players and I need to change us and the system.
"I’m going to have to say it, there are some players that aren’t good enough to get in the team.
"It’s hard for me to say but we’re just not going to go where I want us to go, I need to sort it out very quickly.
"The performance in the second half was like a team you’ve probably been watching at the start of the season in the last two years, we just threw the game away.
"Luckily for me there has only been two games gone in the season and I want to sort it out as quickly as I can.
"I want us to try and play, I want us to be better on the ball and move the ball quicker.
"I’m going to have to change it, if I feel as though that’s the team to get us up the league, unfortunately I don’t think it is with that second half performance."
